To a, IF/110.177, l'l Inn/y concern: I ical-or enlarged onits under sideand is then Be it known that I, JAMES F. MoELRoY, a passed down throughthe art and is sur- 5 citizen of the United States,'residing atAlrounded by a spring F, W ich draws downbany, county of Albany, andState of New ward on the In, and hence on the latch.

5 York, haveinyented certain new and useful I The head of t e pin bearson the cal: of a ljmproi 'cnients in Hose-Couplers, of which. ridge onthe upper side of the late and by "the following specification andaccompany" ifig drawings disclose, as an illustration, oneembodimentthereof whichI now regard as I o the best out of the variousforms in which theprinciples of the invention'may be applied' In thedrawings, Figure l-is a side eleva tion. Fig. 2 is a plan. 3 is a frontend elevation.

I 5 My invention relates to hose-couplers for use in the steam heatingof railway-vehicles, and is of the type wherein the coupler is made intwo complementary parts, each pro' Vided with a project ing side wingadaptedto 2o overlap and engage with the other art.

It relates in particular to a coup er ofthat type wherein asupplementary spring-latch the hole in the latch the latch na be liftedat its outer end and moved vertica y a limite distance against the forceof the spring F. In this movement the latch practically turns onits-rear loweredge' as a center. The normal I 65 in Figs. -2 and 3,wherein it is re resentedas- 1 extending forwardly and paralle to theaxis A of the coupler, but at one side of the body portion A and overthe place occupied by the 7 wing of the adjacent half of t e couplerwhenthe two halves. are engaged with each other. The latch may, however, beturned by hand 7 outwardly away from the body A around the pin E as acenter, so as to be'out of. the way 7: of the coupler-wing. It Wlll benecessary to H fnient of the-two parts without, however, preventingtheir dlsengagement when sufficient 1 fdrce is applied to draw themapart; and'it I censists in a spring-latch pivoted or other-- I halvesare in place, or it may be left in its 80 uiise mounted on one part andalso mounted turned-out position if it is notto be-used. on the nozzleportion of the couplerwhich When, however, the two halves are to-be un-3 o "lies back of the body portion and is separable coupled by turningthem in the well-known tli erefrom. By t 's means a new body orwayaround the lower edges of their meeting reason of this feature and theenlargement of 60 tion may be applied without disturbing the faces as a'center, then the win s will tend to latch and without the need of a newlatch. lift the outer ends of the latches against the In existingcouplers also unprovided with a I face of their retaining-springs F, andthe.

new nozzle portion with the latch mounted and allow the latches to liftand permitthe therein instead of providing a whollyv new escape ofthewings therefrom. It will also go coupler. be observed that, if desired,the under side of Referring to the drawings, A represents the-projectingportion of the latch ma be 4o th e body portion of one half of a couplerslightly inclined downward below the evel frontwhich projects forwardlythe side wing of the upper edge of the part on which the B tooverlapafidengagewith the comple-- latch is seated; Then if the upperside of the 5 mentary half engaging wing lies on the level of said seatthe I of the coupler in a well-known manner. The bodyA also carries theusual outer end of the latch will be slightly lifted packing-gasket.when in position on the top of t e wing and Back of the body portion Ais the nozzle so cause the spring to exert a positive deportion 0,havlng on one side the hose-noz I pressing effect on the wing, tendmg tomake 10 zle Gprojecting therefrom and on the other side having'theseparable body portion A, secured thereto by bolts (1- a. On the nozzleportion .0 is mounted a latch D, which is. pivoted thereto on a verticalpin E, which passes through an opening in the latch that Is con-- Itengage more firmly with the lug on'thc two positions by a lugpn theunder side of its rear projection that isadalpted to drop 1nto'1 o 5 oneor the other of two sl al T the upper surface of the seat on which thelatch rests. While this is the preferred form of latch, other forms maybe substituted Since the latch is mounted on the nozzle ortion C, it isindependent of any removal 0 the body portion A, with the resultsalready mentioned.

I do not herein claim, broadly, the idea of an automatically-releasingspring-latch pivoted to swing into and out of a position over hangingthe complementary coupler part, as this is made the subject of aseparate application, Serial No. 198,285.

What I claim as new, and desire to secure by Letters Patent, is-' 1 Ahose-coupler half comprising a body portion formed with a gasket-face, aforwardly-projecting wing adapted to interlock with the complementarycoupler half,

and a lug adapted to interlock with the Wing of said complementary half,a nozzle portion separably connected with said body portion, and asupplementary latch mounted on said nozzle portion and ada ted to engagethe complementary coupler alf.

' 2) The combination with a coupler half,

having separable nozzle and body portions, the latter provided with aforwardly-projecting side wing to overlap and engage with a similarcomplementary half, of a supplementary spring-latch mounted on thenozzle portion and adapted to engage with the com plementary part whensaid part is in its interlocking position.

3. The combination with a coupler half, having a side wing to overlapand en age a complementary half and also provided separable nozzle andbody portions, of a pivoted latch mounted on the nozzle portion butadapted to be turned inwardly to overhang with the complementary halfwhen in its inter- I looking position, and a spring serving to retainthe atch but adapted to yield to permit the uncoupling of the twohalves.

In witness whereof I have hereunto set my hand, before two subscribingwitnesses, this 16th day of March, 1904.
